AUTOMATIC TRAP FOR MICE AND OTHER VERMIN.

Specification of Letters Patent.

Patented Feb. 22, 1916.

Application filed October 11, 1912. Serial No. 725,261.

To all whom it may concern:

Be it known that I, MICHAEL JAEGER, a subject of the German Emperor,residing at Darmstadt, Grand Duchy of Hesse, German Empire, haveinvented certain new and useful Improvements in Automatic Traps for Miceand other Vermin, of which the following is a specification.

The object of the invention is an automatically resetting trap for miceand other vermin with a falling'door or slide for closing the entranceto the trap. This door or slide is raised again into its open positionby a tilting platform, and is held in this position by a see-saw bridgearranged in the trapping chamber of the trap. The present invention isdistinguished from the known traps of this kind by the specialconstruction of the tilting platform, and also by the combination of thelatter with the falling slide or door of the trap entrance, by whichmeans a simplification of the construction and a greater certainty inworking is attained, while only a single intermediary member is providedfor transferring the twisting movement of the see-saw arranged on theshaft of the tilting platform.

The drawings illustrate one form of construction of the invention.

Figure 1 is a longitudinal section; Fig. 2 a front view; and Fig. 3 ahorizontal section through the trapping chamber.

In the drawings a is the trapping chamber of the trap and b the verticalconnecting passage to the chamber 0, under which and on top of thetrapping chamber is arranged the water container d. In the trappingchamber a is arranged in known manner a see-saw e. The front portion ofthis see-saw automatically falls back and carries a prop or support f,which holds the falling slide 9 for the opening it of the trap in itsopen position. The tilting platform arranged over the water containercomprises a rotatable axle c' arranged longitudinally with respect tothe chamber 0. This axle carries a specially formed floor or platform7;, which after disturbance is always automatically brought back to itsnormal position by means of a counterweight 70 provided with a crank islying in the same plane as the falling slide 9, the crank forming theextension of the axle 71 The crank pin 70 carries the counterweight 70At This axle is which loosely connects the tilting platform with thefalling slide 9, so that after the slide has been pulled up theconnecting rod with this crank is again free to go back into itsoriginal position, and likewise the slide can fall down as soon as it isreleased by the support 7. For this reason the slide is provided with aguide eye or ring "9 through which the lower end of the connecting rodpasses loosely, the end of the rod being arranged with a turned up lipor projection Z to engage with this ring.

The platform 71 can turn to either side, as well to the right as to theleft.- In any case, in turning it thereby raises the connecting rod andwith the latter the falling slide 9. The turning movement produced bythe fall of a trapped animal is suflicient to raise the falling slide tosuch a height that it can again rest on'the support f of the see-sawwhich automatically falls into its locking position. I i

In the vertical connecting chamber 6, be tween the trap and the chamber,a safety flap m is advantageously arranged in such a manner that thetrapped animal is prevented from returning into the passage after havingonce passed said flap, by the pointed end thereof which will yield andallow the passage of the animal from Z) to 0 but will effectivelyprevent its return.

Having now particularly described and ascertained the nature of my saidinvention, and inwhat manner the same is to be performed, I declare thatwhat I claim is:

An animal trap of the character described comprising in combination withthe trap door thereof, a support for said door, an operating rod, atrough shaped tilting platform upon said rod, adapted to be tilted toeither side of the same, a crank upon the shaft for said platform, a rodattached to said crank connecting the tilting platform with said doorfor raising the trap door to its seat upon the fall of a trapped animalfrom said platform.

In testimony whereof I afiix, my signature in presence of two witnesses.
